AI Technical Summary

Benefits of technology

The patent text describes a method and apparatus for transmitting data using a combination of a quasi-cyclic shift and a cyclic shift in a channel code. This allows for more efficient data transmission and decoding. The technical effects of this invention include improved data transmission and decoding efficiency, reduced latency, and improved reliability in communication systems.

Problems solved by technology

In a communication or broadcast system, the link performance may be greatly deteriorated by various kinds of channel noises, fading phenomena, and inter-symbol interferences (ISI).

Abstract

The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate beyond a 4G communication system, such as LTE. One embodiment of the present invention provides a method for channel encoding in a communication system, the method comprising: encoding second data, using an outer channel code; determining a value corresponding to first data; arranging the encoded second data in a block size unit corresponding to the second data, based on the determined value; and encoding the arranged second data, using an inner channel code.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a 371 of International Application No. PCT / KR2018 / 005094 filed on May 2, 2018, which claims priority to Korean Patent Application No. 10-2017-0056566 filed on May 2, 2017, the disclosures of which are herein incorporated by reference in their entirety.BACKGROUND1. Field[0002]The disclosure relates to a method and an apparatus for channel encoding / decoding in a communication or broadcast system.2. Description of Related Art[0003]To meet the demand for wireless data traffic having increased since deployment of 4G communication systems, efforts have been made to develop an improved 5G or pre-5G communication system. Therefore, the 5G or pre-5G communication system is also called a ‘Beyond 4G Network’ or a ‘Post LIE System’.[0004]The 5G communication system is considered to be implemented in higher frequency (mmWave) bands, e.g., 60 GHz bands, so as to accomplish higher data rates. To decrease propagation loss of the radio...
